Please read my entry, Toss your cookies (above), as it explains the solution I have found. From what I can best ascertain, the problem is the ability of the site to correctly interpret data from cookies that have been written to the hard drive. As long as the cookies are being read from RAM and not from the cookie file on the drive, the session function seems to work just fine. But the first moment it has to rely on data from the hard drive cookie, it times out. I tested this by deleting all Renderosity cookies, then locking the cookie file so that it could not be overwritten. This insured that no Renderosity cookies would be retained on the drive. Each time I launch the browser and click a page link (other than index, which is free space for everyone, member or not), it redirects me to log in. I use browser memory to autofill the log form. I log in manually and navigate without a single problem. The problem is that you have to delete the cookies every time you start a new session and manually log in each time (or lock the cookie file and forget deleting them).
